Abstract. From enrichment cultures established for purple nonsulfur bacteria using water and sediment samples from Lake Bogoria and Crater Lake, two soda lakes in the African Rift Valley, three strains of purple nonsulfur bacteria were isolated; strain LBB1 was studied in detail. Cells of strain LBB1 were motile and spherical to rod-shaped, suggesting a relationship to Rhodobacter or Rhodovulum species, and the organism was capable of both phototrophic and chemotrophic growth on a wide variety… 

Rhodobaculum claviforme gen. nov., sp. nov., a new alkaliphilic nonsulfur purple bacterium

Pairwise comparison of the nucleotides of the 16S rRNA genes revealed that strains B7-4 and B8-2 belonged to the same species and were most closely related to the aerobic alkaliphilic bacteriochlorophyll a-containing anoxygenic phototrophic bacterium (APB) Roseibacula alcaliphilum DeT and to NPB strains Rhodobaca barguzinensis VKM B-2406T and Rbc.

Rubribacterium polymorphum gen. nov., sp. nov., a novel alkaliphilic nonsulfur purple bacterium from an Eastern Siberian soda lake

An alkaliphilic nonsulfur purple bacterial strain “Green” was isolated from sediments of the littoral zone of the soda lake in the Barguzin River valley (Eastern Siberia) and analysis of 16S rRNA gene sequences revealed a 10% difference with the most closely related NPB (Rhodobacter species).

Rhodobaca barguzinensis sp. nov., a new alkaliphilic purple nonsulfur bacterium isolated from a soda lake of the Barguzin Valley (Buryat Republic, Eastern Siberia)

A novel strain, alga-05, of alkaliphilic purple nonsulfur bacteria was isolated from sediments of a small saline soda lake near Lake Algin (Barguzin Valley, Buryat Republic, Russia), and was described as a new species of the genus Rhodobaca.

Rhodovulum steppense sp. nov., an obligately haloalkaliphilic purple nonsulfur bacterium widespread in saline soda lakes of Central Asia.

Seven strains of purple nonsulfur bacteria isolated from the shallow-water steppe soda lakes of the cryoarid zone of Central Asia formed a genetically homogeneous group within the genus Rhodovulum, according to genotypic and phenotypic characteristics.

Thiocapsa imhoffii, sp. nov., an alkaliphilic purple sulfur bacterium of the family Chromatiaceae from Soap Lake, Washington (USA)

The unique assemblage of physiological and phylogenetic properties of strain SC5 defines it as a new species of the genus Thiocapsa, and it is described herein as Tca.

Roseibacula alcaliphilum gen. nov. sp. nov., a new alkaliphilic aerobic anoxygenic phototrophic bacterium from a meromictic soda lake Doroninskoe (East Siberia, Russia)

A bacterial strain De was isolated from the surface water layer of the meromictic soda lake Doroninskoe and similarity between the isolate and the known alkaliphilic genera of nonsulfur purple bacteria (Rhodobaca) was 96%, sufficient for the description of a new genus of aerobic anoxygenic phototrophic bacteria.

The new alkaliphilic bacteriochlorophyll a-containing bacterium Roseinatronobacter monicus sp. nov. from the hypersaline Soda Mono Lake (California, United States)

Two strains of pink-colored aerobic bacteriochlorophyll a-containing bacteria were isolated from aerobic and anaerobic zones of the water column of Mono Lake and were assigned to a new species of the genus Roseinatronobacter, Roseinatomobacter monicus sp.

Heliorestis daurensis, gen. nov. sp. nov., an alkaliphilic rod-to-coiled-shaped phototrophic heliobacterium from a Siberian soda lake

This unique assemblage of properties implicates strain BT-H1 as a new genus and species of the heliobacteria, Heliorestis daurensis, named for its unusual morphology and for the Daur Steppe in Russia in which these soda lakes are located.

Selective enrichment and characterization of Roseospirillum parvum, gen. nov. and sp. nov., a new purple nonsulfur bacterium with unusual light absorption properties

Because of the large phylogenetic distance to known phototrophic species of the α-Proteobacteria and of its unique absorption spectrum, strain 930I is described as a new genus and species, Roseospirillum parvum gen. and sp.

Rhodopseudomonas acidophila, sp. n., a new species of the budding purple nonsulfur bacteria.

A succinate-mineral salts medium of pH 5.2 provided selective enrichment conditions for Rhodomicrobium vannielii and for a new species belonging to the Athiorhodaceae, described herein as Rhodopseudomonas acidophila, which can grow either under anaerobic conditions under the light or under microaerophilic to aerobic conditions in the dark.

A new genus of marine budding phototrophic bacteria, Rhodobium gen. nov., which includes Rhodobium orientis sp. nov. and Rhodobium marinum comb. nov.

A phylogenetic analysis based on 16S rRNA gene sequences revealed that strain MB312T (T = type strain), a representative of the new phototrophs, was a member of a lineage that was distinct from members of the genus Rhodobium; Rhodopseudomonas marina was the closest relative.
